The present invention relates to a tag using RFID (Radio Frequency IDentification) technology, and more particularly, it can be applied irrespective of the type and shape of the object requiring auto-identification, and can be used for various purposes. It's about tags.

The RFID tag generally refers to a device composed of an IC chip, an antenna, and adhesive materials, and transmits and receives data with an external reader or interrogator, and is also called a transponder. The RFID tag transmits and receives data with the reader in a contactless manner. Inductive Coupling, Backscattering, Surface Acoustic Wave (SAW), etc. may be used depending on the height of the frequency used, and Full Duplex (FDX) using the electromagnetic wave. , Data can be transmitted and received to and from the reader in a half duplex (HDX: Half Duplex) and sequential (SEQ).

For example, the RFID tag is used for the management of goods due to the nature of the non-contact method, and is used in various ways such as an IC card or a pass for payment. In view of the frequency band, a low frequency band such as 135 KHz and 13.56 MHz has been widely used in the related art, but in recent years, the use of the UHF (Ultra High Frequency) region of the 900 MHz band has increased significantly. In particular, large retailers such as Walmart and the US Department of Defense use RFID for logistics management. In this case, the frequency of the UHF band using backscattering is mainly used, and it operates manually without external batteries. Passive tags that generate the required current are once accepted as standard.

Recognition method using RFID technology includes the tag itself, the method of integrating into a card made by laminating, the method of using an adhesive medium such as a sticker, and the injection molding of the tag. And shaping into a mold.

As a conventional example, the method of directly inserting the tag itself without additional adhesion to parcels or clothes has the advantage that it does not need to be fastened and can be reused, but the risk of loss or loss is great and the tag is easily damaged by external impact. It has the disadvantage that it can be.

In addition, the laminating card has the advantage of protecting the RFID chip from external environmental changes and being easy to carry by a user, such as a wallet. However, since the laminating card is difficult to attach or fasten to a product, the application area is extremely limited. Has disadvantages In addition, it is expected to be the most popular and universal method compared to the above-mentioned method in the form of a sticker, but also has a limitation in holding power and stability in a harsh environment.

In addition, the tag formed through the molding has the advantage that it can be used in the harsh environment because it protects the RFID chip inside, but once the tag produced by molding can not be used for other purposes by separating the RFID parts separately, it is impossible to recycle. Injection molding itself has the disadvantage that the processing process is complicated and relatively expensive compared to other forms of use.

As already mentioned, an RFID tag consists of an IC chip, an antenna and a binding material. Basically, a film-shaped substrate made of various plastic materials such as PVC, PCB, PE, PA, and PAT is used, and the substrate is generally formed to a thickness of about 100 μm, and an antenna portion is formed thereon. Is formed. The conducting wire of the antenna unit may be mounted on the substrate together with the chip or connected to an IC chip outside the film by a direct bonding method or a chip on board (COB) method. The RFID tag may be partially coated with epoxy resin or the like for stability of the connection between the IC chip and the antenna lead.

In general, the size of the RFID tag depends on various features such as the size of the chip, the size of the antenna, the technical skill in the process, and whether the battery is installed according to the active / passive method. In recent years, the technical level of chip size and technical proficiency is remarkably improved, and the size of the RFID tag mainly depends on the size of the antenna. The size of the antenna is mainly larger as the reading range required by the reader is larger, the smaller the radiation power of the reader, and the smaller the higher the frequency used. In the case of data transmission and reception by backscattering using frequencies in the UHF band or more, the degree of backscattering depends on the size, shape, geology, surface structure and wavelength, and polarization of the antenna. Better efficiency at the antenna

To sum it up, in the case of the existing 13.56MHz frequency tag that is commonly used, the antenna should be formed by the coil method by the inductive coupling method, the antenna size should be more than several meters, and the outer housing should be made of metal There was a fundamental limitation, such as not being available, but as the RFID method using a frequency and backscattering of about 900 MHz or more is widely used in the area of logistics and the like, the size of the antenna and the material of the housing are alleviated.

In particular, it is possible to use the housing of the metallic material, it is possible to further reduce the size of the antenna and tag. In addition, in the case of the backscattering method, the directional problem between the reader and the RFID tag is greatly alleviated compared to the inductive coupling method, so that the limitation on the form of the tag may be alleviated.

As already mentioned, the form of the conventional RFID tag is 1) limited in adhesion holding in harsh environments, 2) difficult to maintain chip stability in harsh environments, and 3) tag manufacturing process, especially antenna It has at least one or more of problems such as complicated manufacturing process and high cost.

One object of the present invention is to provide an RFID tag that can be easily fastened or mounted using an existing eyelet fastening device or an improved eyelet fastening device, and at the same time, adhesive holding force or chip compared to an existing RFID tag. It is to provide an RFID tag having an advantageous structure to maintain the stability of the.

It is another object of the present invention to simultaneously perform the RFID tag function while satisfying the fastening of the existing eyelet base and the hole holding function of the object and the fastening complementary function of the eyelet base or the rivets of the eyelet washer. To provide an RFID tag.

It is still another object of the present invention to provide an RFID tag that can facilitate recycling of a tag by using a metallic eyelet such as aluminum, which has already reached a high level of recycling, as an antenna.

It is another object of the present invention to provide an RFID tag having an advantage in manufacturing cost and process because it takes an advantage in the raw material price of the RFID tag, and is economical by simplifying the antenna manufacturing process, and does not use a separate adhesive material for fastening. It is.

It is still another object of the present invention to provide an RFID tag that can minimize the space and proportion of the tag itself by using the metallic eyelet itself as an antenna.

Finally, another object of the present invention is to provide an RFID tag having a structure capable of expressing various shapes, shapes, and colors, which can be usefully used for purposes other than tags.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, an RFID eyelet includes an eyelet base and an RFID circuit module mounted on a slit formed in the eyelet base, and the eyelet is formed by the slit. The current flow in the base is restricted and flows through a certain path so that the terminals of the RFID circuit module are connected to separate parts, so that the eyelet base is used as a dipole antenna.

Eyelets have already been used in various fields, fastening devices and manufacturing methods are also widely spread and has the characteristics that mass production is advantageous. Therefore, the manufacturing cost is significantly lower than that of the conventional RFID tag, which is expensive. In using the structure of the eyelet made of a conductive material, the eyelet itself is used as an antenna using a slit.

The upper portion of the eyelet base is a ring portion including a slit, and the lower portion is a fixing portion fixed through the object. The ring portion includes an upwardly projecting portion in the vicinity of its inner circumference, and is formed of a flat plate from the point where the protrusion is formed to the outer circumference. The ring portion includes a cap that surrounds the ring portion to prevent deformation of the ring portion when the fixing portion is processed to catch the object.

The cap is transparent so that the slits of the ring portion are visible. This is to identify the RFID circuit module mounted on the lower surface of the eyelet base to indicate the purpose of the eyelet base. In addition, the cap is bent end is bent by the ring portion is fixed to the lower portion, the thickness of the cap is made of 0.5mm, the length of the bent end is preferably made of 3 ~ 4cm.

In addition, the fixing part is composed of a plurality of legs extending downward from the inner peripheral portion of the ring portion is arranged at a predetermined interval, the tricycle form is preferably arranged at a predetermined interval in the lower portion of the ring portion.

In addition, when the fixing portion of the eyelet base passes through the object to fix the eyelet base itself to the object, after the plurality of legs forming the fixing portion pass through the object, the lower end of the leg is formed by a concave grooved press block. Compressed, the leg is wound along the groove toward the object to secure the eyelet base to the object. Alternatively, the eyelet base may be fixed to the object by bending the fixing part outward.

At this time, the press block for pressing the fixing part of the eyelet base is paired with a fixing block fixing the ring part of the eyelet base at the top to fix the eyelet base to the object.

In addition, an RFID circuit module for performing an RFID function is formed in the form of an IC chip and is mounted by die bonding under the slit formed on the capped eyelet base, and the eyelet base is formed of a metal material to form an antenna of the RFID circuit module. Function

In this case, when the frequency band of the RFID circuit module is about 2 GHz or more, the eyelet base may sufficiently perform the antenna function even with the conventional eyelet size. However, when the frequency band is about 900 MHz, the eyelet base may have an antenna size. You may not be able to perform enough functions.

For example, in the frequency range of about 900MHz or more, the dipole antenna of the RFID circuit module should be at least about 15 ~ 16cm to enable smooth communication between the RFID circuit module and the reader, but the eyelet connected to the RFID circuit module as the antenna is about 15cm in size. Eyelet may be faded in its original function when manufactured with.

In order to solve this problem, the RFID eyelet according to the present invention can extend the size of the antenna to the RFID circuit as necessary by electrically connecting the antenna extension to the eyelet base.

The antenna extension part may be formed of an aluminum tape that can be attached to an object, a paint having conductive properties, a conductive interlayer, and the like, and the size of the antenna may be increased as necessary by being applied on the object. In addition, the process of forming the antenna extension is simple and inexpensive, so it is very easy to commercialize.

In this way, by using the eyelet as an antenna, the manufacturing process of the RFID tag can be significantly simplified compared with the manufacturing process of the conventional RFID tag, and the RFID circuit module can be effectively fixed to the object, which is used in the past. It can maintain and improve eyelet function of. In addition, the conventional eyelet fastening device can be utilized as it is economical in many respects. Eyelet washers and eyelet bases can be used as antennas to effectively protect the IC chip for RFID, and can effectively maintain holding power against harsh external environments by using the eyelet structure that is firmly fixed to the object.

In addition, eyelets are widely used in many fields in real life, and their applications and ramifications can grow tremendously, and their manufacturing and mounting processes are simple, and at the same time, the production facilities system of eyelets is already widely distributed. Has the advantage that can be significantly lowered.

For example, eyelets are currently used in tags used to identify air cargo or train cargo, stock cargoes such as warehouses, and merchandise for sale in various distribution stores. In this case, if the conventional ordinary eyelets are used by replacing them with RFID eyelets, the information on the cargo can be automatically recognized without checking the information, and the cargo or goods can be prevented from being lost or incorrectly delivered in advance.

In addition, RFID eyelets can withstand external shocks and other harsh environments and can protect the RFID chip inside. If the RFID tags are bound to cargo using rubber bands or wires, they can be separated and reused. It is economical.

In addition, even in areas where eyelets are used, such as clothing and shoes, shading tents, and construction materials tents, and even those where eyelets are not currently used, conventional eyelet fastening devices can be used to easily fix RFID eyelets to various objects. Through RFID eyelets, contactless identification technology using RFID can be applied to various fields.

In the conventional eyelet, a conductive material such as metal has not been used as the housing of the RFID tag because it may interfere with transmission and reception between the reader and the RFID tag. However, the present invention uses a metal housing, and since the conductive housing can be used as an antenna, there are many advantages in terms of manufacturing, use, and protection.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

In addition, the fixing part 120 is composed of a plurality of legs (120a, 120b, 120c) extending from the inner circumference of the ring portion 110 to be disposed at a predetermined interval, the predetermined interval at the lower portion of the ring portion 110 As the legs (120a, 120b, 120c) is arranged trivets.

When the fixing part 120 is formed in the shape of the tricycle as described above, the RFID circuit module 125 is easily transported between the tricycles to die-bond the RFID circuit module 125 to the slit 115 formed in the ring part 110. .

At this time, since the RFID circuit module 125 has a very small and sensitive circuit configuration, it is necessary to die bond using fine tweezers. However, such manual work is not suitable for mass production of eyelets for the RFID circuit module 125, and automation work must be possible to lead to mass production of eyelets.

That is, the RFID circuit module 125 is fixed to a picker (Picker) that performs an automated operation for the transport and placement of the RFID circuit module 125 is disposed as a slit 115 of the ring unit 110, RFID circuit module The die 125 is die bonded to both ends of the slit 115 in a state where the 125 is disposed in the slit 115.

You can zoom in as much as you need. In addition, the process of forming the antenna extension 190 is simple and inexpensive, so it is very easy to commercialize.

In addition, the antenna extension 190 may be provided in a printed form by a hot stamping method. By a method such as hot stamping, not only a tape shape, but also a label and a trade name may be displayed.

On the other hand, the eyelet base 110 is generally made of a good malleable and ductile metal material, such as aluminum, brass, iron, these materials also have good characteristics as an antenna of the UHF band because the degree of backscattering is very high.

When the RFID eyelet 10 passes close to the reader-writer device, a signal for a data request is received from the reader-writer device, and a signal received from the antenna extension 190 and the eyelet base 100. In response, the RFID circuit module 125 may generate a signal or modify data stored internally. At this time, the RFID circuit module 125 is physically protected by the eyelet base 100 made of metal.

At this time, the object (OBJ) is bound to the cargo, etc. may be a tag indicating the destination and the origin of the cargo, various mail, parcels, logistics packaging materials, clothing tags, cargo tents, etc., of course, in a large distribution mart It can also be used to package products for sale.
